Abstract：

Aiming at the possible wrinkles or cracks during the forming process of anti-collision beam of vehicle front bumper, the finite element simulation of process was carried out based on Dynaform. The forming limit, thickness change and stress and strain state of anti-collision beam of vehicle front bumper were studied according to the simulation results, and the comparison of simulation results and actual forming parts was made. A comparative analysis of thinning rate in some large deformation area of parts was carried out especially, and a consistency between simulation results and actual deformaction was achieved. The results show that simulation analysis can aovid the wrinkling and cracking defects,improve the forming quality effectively,reduce the production costs, shorten the manufacturing cycle of mold design, and improve the level of design and production.
